|---|---|---|---|
| 2016 | 15-15 MPG | $5,300-$5,300 | 1 |
| 2017 | 15-15 MPG | $5,300-$5,300 | 1 |

How it compares
Against the average standard sport utility vehicle 4wd in this dataset (about 23 MPG), the LX sits roughly 8 MPG below that mark on average, making it a thirstier-than-average choice for its class.
Five-year fuel cost
Fuelling a LX for five years at the EPA's 15,000-mile basis costs roughly $26,500 to $28,500, averaging about $27,500 across the versions here. That is the energy bill alone — it excludes insurance, maintenance and depreciation, which for most owners together exceed what goes into the tank.
How it changed over time
Between 2016 and 2020 the LX's average combined economy slipped from about 15 to 14 MPG. Redesigns, new engines and added hybrid or electric versions are usually what move the number, so the year you choose can matter as much as the model.
Best year for fuel economy
The 2019 LX has the strongest average combined economy in this database at about 15 MPG, while the 2020 is the lowest at about 14 MPG. If running cost is your priority, that is the year to target on the used market; later years may add equipment or safety features instead.
